INDEX-BOOK.

SPECIFICATION forming part Of Letters Patent No. 680,044, dated. August6, 1901. Application filed November 11 1899- Serial No. 736,574. Nomodel.)

To all whom it may concern.- a

Be it known that I, LEO HIRSOH, a citizen of the United States, residingat Chicago, Cook county, Illinois, have invented certain new and usefulImprovements in Index-Books, of which the following is a specification.

The invention relates particularly to books in which indexing-pages arenecessary, and especially to the means for facilitating the finding ofnames, &c.

The object of the invention is to provide a 1 simple, economical, andefficient indexingbook; and the invention consists in the features anddetails hereinafter described and claimed.

The accompanying drawing represents a perspective view of an open bookconstructed in accordance with my improvements.

In illustrating and describing my improvements I prefer to illustrateand describe them in connection with a regular book; but it will beunderstood that I do not desire to be unduly limited thereby, as it willreadily be seen that the covers are not actually necessary and thatthere can be any number of leaves from one to one hundred.

In constructing a book in accordance with my improvements I prefer touse the covers A and A and between such covers to insert a plurality ofleaves B. Any one or more of these leaves are provided with a pluralityof horizontal lines 0, which form the namespaces 0, arranged at one sideof the page, as shown, and adjacent to the name-spaces the page has aplurality of vertical lines D, crossing the horizontal lines, so as toprovide small spaces or squares d, in which indicating-numerals or othercharacters may be written, as hereinafter more fully described.

indicates the number of words in the name, I

and tracing the horizontal column to the right he readily finds the namesought. In this way the bookkeepers time is economized. In place of anumeral the third letter of the first name may be used in the square ornumeral spaces.

I claim In a system of indexing, a vertical column divided into spacesby horizontal lines and having names entered in the spaces, verticalcolumns adjacent to the name-column headed by the letters of thealphabet and divided into spaces by the horizontal lines dividing thename-column, and a numeral for each name designating the number of wordsin the name entered in a space both in alinement with the name and alsoin the column headed by a letter representing a letter arbitrarilyselected from its numerical position in the name, substantially asdescribed.
